I have three of the Rossi 92 clones, a stainless 20" carbine in 38/357, a blued 20" carbine in 44/40 Win. and a blued 24 " half round/octagon rifle in 45 Colt. Just as a general statement across the board, I think one can expect smoother problem free feeding using a rounded profile bullet (flat point OK) than one with a 'sharp edge' like WC and SWC. That said, I don't recall having any problems in my 38/357 with any of my handloads. I'd suggest you load up a few to try, before laying in a large supply.
